Not right or wrong move.... if you do wedding as a job, I wonder why you would consider a 1Dx instead of a 5D3 or two... just like you said you make pj and no posed photograghy.... and you were disappointed there are no joystick in your 1Ds3..... while you love the files from your 1Ds3....

What you are having now is GAS.... not what you really need my friend.... if you need a cam for wedding... go 5D3
